What Is PDF Translation With Original Formatting?

PDF translation with original formatting, also called zero-layout-loss translation, is the process of translating PDF content while keeping all fonts, columns, headers, footers, tables and images identical to the source file.

Unlike basic translation tools that extract only flat text from PDFs, format-preserving tools recognize semantic document structure to retain all visual and functional elements of the original file.
